Impact of IRP deficiency on the proteome of Ly6G+ cells from the bone marrow in mice


ABSTRACT: The overall objective of the project is to evaluate the effects of loss of function of iron regulatory proteins (IRP1, encoded by Aco1)-1 and -2 (IRP2, encoded by Ireb2) during adult life. Mice carrying floxed Aco1 and Ireb2 alleles were crossed to a knockin strain expressing a tamoxifen-inducible CRE recombinase under the control of the Rosa26 promoter. The resulting Aco1flox/flox,Ireb2flox/flox,Rosa26+/CreERT2 mice are designated P1/2-KO; littermates lacking the CreER sequence (Aco1flox/flox,Ireb2flox/flox,Rosa26+/+) serve as reference and are designated P1/2-CTR. Adult mice were injected (i.p.) with tamoxifen on day 1 and day 3 to ablate the IRPs in the whole body, and were sacrificed on day 10 for analysis. Bone marrow cells were collected and LY6G+ cells were magnetically sorted for proteome analysis by LC-MS/MS using an Ultimate 3000 UPLC system connected to an Orbitrap Exploris 480 mass spectrometer.

Iron is mostly devoted to the hemoglobinization of erythrocytes for oxygen transport. However, emerging evidence points to a broader role for the metal in hematopoiesis, including the formation of the immune system. Iron availability in mammalian cells is controlled by iron-regulatory protein 1 (IRP1) and IRP2. We report that global disruption of both IRP1 and IRP2 in adult mice impairs neutrophil development and differentiation in the bone marrow, yielding immature neutrophils with abnormally h  ...[more]
